Payers are increasingly using episodes of care to measure and reward efficiency in health care. Much attention has been paid to the effects of different rules for assigning episodes to providers, but little to how individual costs are assigned to episodes. In this paper, we studied the extent to which the two most widely-used commercially available episode(More)
Patient Safety Indicators (PSIs), developed by the Agency for Healthcare Research and Quality (AHRQ), are administrative data-based indicators that identify potential in-hospital patient safety events. This study developed and tested methods for (1) applying PSIs to Department of Veterans Affairs (VA) discharge data, and (2) comparing VA with non-VA PSI(More)
BACKGROUND Providers use risk-adjustment systems to help manage healthcare costs. Typically, ordinary least squares (OLS) models on either untransformed or log-transformed cost are used. We examine the predictive ability of several statistical models, demonstrate how model choice depends on the goal for the predictive model, and examine whether building(More)
PURPOSE To determine whether the 2003 Accreditation Council for Graduate Medical Education (ACGME) duty hours reform affected medical knowledge as reflected by written board scores for internal medicine (IM) residents. METHOD The authors conducted a retrospective cohort analysis of postgraduate year 1 (PGY-1) Internal Medicine residents who started(More)
BACKGROUND Personal health records (PHRs) have the potential to improve patient self-management for chronic conditions such as diabetes. However, evidence is mixed as to whether there is an association between PHR use and improved health outcomes. OBJECTIVE The aim of this study was to evaluate the association between sustained use of specific patient(More)
BACKGROUND Adverse drug event (ADE) detection is an important priority for patient safety research. Trigger tools have been developed to help identify ADEs. In previous work we developed seven concurrent, action-oriented, electronic trigger algorithms designed to prompt clinicians to address ADEs in outpatient care. OBJECTIVES We assessed the potential(More)

The Agency for Healthcare Research and Quality (AHRQ) is the lead Federal agency charged with supporting and conducting research that will improve the quality, safety, efficiency, and effectiveness of health care for all Americans. Findings from AHRQ research are used by health care decisionmakers–including patients and clinicians, health system leaders,(More)
Objective: We compared discharges from teaching and nonteaching hospitals for relative rates and likelihood of potentially preventable adverse events. Methods: We applied Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators (PSIs) to adult male patient discharges from Veterans Health Administration (VA) and non-Federal hospitals,(More)
Objective: The Patient Safety Indicators (PSIs) developed by the Agency for Healthcare Research and Quality identify potential patient safety events through administrative records. We sought to determine whether there were racial disparities in patient safety event rates in Veterans Health Administration (VHA) hospitals. Methods: We explored 5 years of VHA(More)
